Study on the Spatial Distribution and Relationship of Heavy Metal Elements of Latosol in Eastern and Western of Hainan Island
摘要
Abstract
[ Objective ] To study the spatial distribution and relationship of heavy metal elements (HMEs) of latosol in eastern and western of Hainan Island. [ Method ] Taking the latosol of Hainan Island as research areas, and using on-site sampling and laboratory analysis testing methods, the content and the spatial distribution characteristics of 7 HMEs in 35 soil samples which were derived from 12 latosol profiles in both the East and West areas were studied. [ Result] The results indicated that content range of HMEs in both eluvial horizons and illuvial horizons had a positive correlation with the content range in parent material horizons. For most of HMEs except Ni, the contents of HMEs in different horizons were lower than its average contents in the southern latosol of the China. Part of the heavy metal element was accumulated in the deposition layer. Heavy elements in the soils can be enriched in the latosol profiles because of the influence of human' s activities. Cr and Ni, Cr and Zn also had positive significant relationships, so the results showed that theses HMEs in latosol of Hainan Island have the same source of pollution. [ Conclusion] These primary research results might provide the basis for the risk assessment of heavy metal contamination of latosol in eastern and western of Hainan Island.关键词
